> We want to merge the standard atomics patch immediately after 23.07 release. This means, the patches need to be reviewed/tested/ready-to-merge by 12 July 2023 (as per current planning for 23.07). So, the patch submission needs to happen earlier.

yes, my wording is poor here. i really meant to say can be merged as
soon as 23.07 is released which as you note implies we want to review
prior to that release.
